10:49 <_florent_> promach3: TDQS/ODT are optional, for a first controller, I would recommend not using them. In addition the Micron datasheet/application notes (that are very clear and well written) I would recommend having a look and grep in the LiteDRAM code, this can probably answer some of your questions.

10:50 <_florent_> tWR is for example used to compute the Precharge Time here: https://github.com/enjoy-digital/litedram/blob/e5f4f828ad781a38c1ce99186819d75c0b878b39/litedram/core/bankmachine.py#L146

10:52 <_florent_> In LiteDRAM we are not using TDQS/TDQS# but using DM, so as outputs

10:54 <_florent_> promach3: you can find a generated core here and the DRAM IOs here: https://github.com/chipsalliance/Cores-SweRVolf/blob/master/cores/litedram/litedram_core.v#L10-L24

11:21 <pftbest> _florent_: hello, maybe you had a chance to try etherbone on your ecpix-5 board?

14:11 <nats`> Hello, I'm starting to think about using litex for few board, I red the wiki on github but I was wondering if there is an up-to-date basic tutorial, like how to cleanly add board custom file etc

14:22 <keesj> The initial tutorials are quite nice https://github.com/litex-hub/fpga_101 and it something does not work fixing it is a nice intro into litex and the joy of this community

14:25 <keesj> after that I must confes.. so much hard work has been done on boards I used (e.g. arty) that it was not much fun getting them to work

14:26 <keesj> what kind of boards are you thinking about?

15:11 <_florent_> Hello

15:12 <_florent_> pftbest: sorry, I've not been able to have a look at Etherbone/ECPIX5

15:13 <nats`> keesj, a custom board based on an artix for the beginning

15:13 <nats`> I'll check those labs :) thx

15:13 <_florent_> nats`: We indeed still need to write more doc... but looking at the Wiki, fpga_101 and the platforms/targets in LiteX-Boards should allow you to understand how it works

15:14 <pftbest> _florent_: okay, np

15:14 <nats`> I didn't find the fpga_101 in fact

15:14 <_florent_> nats`: But still happy to help and explain things if not clear, that's always nice to get feedback to improve the doc, or at least list the things we need to add to the doc :)

15:14 <nats`> I was stuck in a link loop coming back to the wiki :D

15:15 <_florent_> nats`: Which kind of peripherals do you have on your board? (just to know which board is maybe more appropriate to be used as a reference)

15:16 <nats`> Gbps phy, serial port and few other stuff, but NO external RAM

15:16 <nats`> that's the challenge

15:18 <_florent_> ok I see, the Gbps Ethernet PHY is GMII/RGMII?

15:18 <nats`> RGMII it's a 88E1512

15:21 <_florent_> nats`: OK, then you can probably use the Nexys Video as a reference

15:21 <_florent_> https://github.com/litex-hub/litex-boards/blob/master/litex_boards/platforms/nexys_video.py

15:21 <_florent_> https://github.com/litex-hub/litex-boards/blob/master/litex_boards/targets/nexys_video.py

15:21 <nats`> I'll check that at home this evening :)

15:24 <_florent_> Or the Genesys2 that is a Kintex7 but also has a RGMII PHY

15:25 <_florent_> nats`: I would recommend starting very simple: To begin you only need an input clock, a led if possible and a UART

15:25 <_florent_> With this you should be able to build a very simple LiteX SoC

15:25 <nats`> yep the classic :)

15:25 <_florent_> then you can add the Ethernet + your custom peripherals
